Signs Your Detroit Diesel DOC May Need Inspection or Replacement
- Difficulty reaching or maintaining exhaust temperatures needed for DPF regeneration
- Frequent, incomplete or unsuccessful regeneration cycles
- Diagnostic trouble codes related to DOC catalyst efficiency or exhaust temperature response
- Excessive soot loading in the downstream DPF
- Fuel, oil or other contamination visible at the catalyst inlet
- Increased exhaust backpressure or reduced engine performance
- Cracking, melting, corrosion or other physical damage to the catalyst substrate or housing
These symptoms may have multiple causes and do not automatically mean the DOC must be replaced. Diagnose the complete engine, fuel, turbocharger, sensor and exhaust aftertreatment systems before replacing the DOC.
